26.

Factorise 8(a+1)^2+2(a+1)(b+2)-15(b+2)^2

Answer»

$\bf\,8(a+1)^2+2(a+1)(b+2)-15(b+2)^2$

$=8m^2+2mn-15n^2$ $\text{ wherre m=a+1 and n=b+2}$

$\textbf{Using middle term factorization}$

$=8m^2+12mn-10mn-15n^2$

$=4m(2m+3n)-5n(2m+3n)$

$=(2m+3n)(4m-5n)$

$=(2(a+1)+3(b+2))(4(a+1)-5(b+2))$

$=(2a+2+3b+6)(4a+4-5b-10)$

$=(2a+3b+8)(4a-5b-6)$

$\therefore\bf\,8(a+1)^2+2(a+1)(b+2)-15(b+2)^2=(2a+3b+8)(4a-5b-6)$

38.	Solve sinx +sin5x=sin3x
Answer» ∴ $x$ have FOUR DIFFERENT VALUES; $x=\frac{2\pi n}{3}$ , $\:x=\frac{\pi }{3}+\frac{2\pi n}{3}$ , $x=-\frac{\pi }{6}-\pi n$ and $x=-\frac{5\pi }{6}-\pi n$ Step-by-step EXPLANATION: GIVEN; $sinx+sin5x=sin3x$ ⇒ $sinx+sin5x-sin3x=0$ ⇒ $2sin\frac{x+5x}{2} cos\frac{x-5x}{2} -sin3x=0$ ⇒ $2sin(3x)cos(-2x)-sin(3x)=0$ ⇒ $sin3x(2cos(-2x)-1)=0$ ⇒ $sin 3x=0$ or $2cos(-2x)-1=0$ ∴ $sin 3x=0$ ⇒ $3x=0+2\pi n$ , $\:3x=\pi +2\pi n$ ∴ $x=\frac{2\pi n}{3}$ , $\:x=\frac{\pi }{3}+\frac{2\pi n}{3}$ And, ∴ $2cos(-2x)-1=0$ ⇒ $cos(-2x)=\frac{1}{2}$ ⇒ $-2x=\frac{\pi }{3}+2\pi n$ , $-2x=\frac{5\pi }{3}+2\pi n$ ∴ $x=-\frac{\pi }{6}-\pi n$ , $x=-\frac{5\pi }{6}-\pi n$ So, $x$ have four different values; $x=\frac{2\pi n}{3}$ , $\:x=\frac{\pi }{3}+\frac{2\pi n}{3}$ , $x=-\frac{\pi }{6}-\pi n$ and $x=-\frac{5\pi }{6}-\pi n$

38.

Solve sinx +sin5x=sin3x

Answer»

∴ $x$ have FOUR DIFFERENT VALUES;

$x=\frac{2\pi n}{3}$ , $\:x=\frac{\pi }{3}+\frac{2\pi n}{3}$ , $x=-\frac{\pi }{6}-\pi n$ and $x=-\frac{5\pi }{6}-\pi n$

Step-by-step EXPLANATION:

GIVEN;

$sinx+sin5x=sin3x$

⇒ $sinx+sin5x-sin3x=0$

⇒ $2sin\frac{x+5x}{2} cos\frac{x-5x}{2} -sin3x=0$

⇒ $2sin(3x)cos(-2x)-sin(3x)=0$

⇒ $sin3x(2cos(-2x)-1)=0$

⇒ $sin 3x=0$ or $2cos(-2x)-1=0$

∴ $sin 3x=0$

⇒ $3x=0+2\pi n$ , $\:3x=\pi +2\pi n$

∴ $x=\frac{2\pi n}{3}$ , $\:x=\frac{\pi }{3}+\frac{2\pi n}{3}$

And,

∴ $2cos(-2x)-1=0$

⇒ $cos(-2x)=\frac{1}{2}$

⇒ $-2x=\frac{\pi }{3}+2\pi n$ , $-2x=\frac{5\pi }{3}+2\pi n$

∴ $x=-\frac{\pi }{6}-\pi n$ , $x=-\frac{5\pi }{6}-\pi n$

So, $x$ have four different values;

$x=\frac{2\pi n}{3}$ , $\:x=\frac{\pi }{3}+\frac{2\pi n}{3}$ , $x=-\frac{\pi }{6}-\pi n$ and $x=-\frac{5\pi }{6}-\pi n$

Answer» RowseNotessearch HOMEWORK HELP > MATH If LOG x^3- log 10x = log 10^5 find x PRINT Print document PDF list Cite Expert Answers HALA718 \| CERTIFIED EDUCATOR log x^3- log 10x = log 10^5 We will use logarithm properties to solve for x. We know that log a - log b = log a/b ==> log x^3 - log 10x = log x^3/10x = log x^2/10 ==> log x^2/10 = log 10^5 Now we have two equal logarithm with equal bases. Then, we conclude that the logs are equal. ==> x^2 /10 = 10^5 Now let us multiply both sides by 10. ==> x^2 = 10^5 * 10 We know that x^a * x^b = x^(a+ b) ==> x^2 = 10^(5+ 1) ==> x^2 = 10^6 Now we will re-write 10^6. We know that 10^6 = 10^(2*3) = (10^3)^2. ==> x^2 = ( 10^3) ^2 Now we will take the root of both sides. ==> x = 10^3= 1000 ==> Then, the answer is x = 1000.
