(a-2b)^2 - 2(a-2b)(2a-b)+(2a-b)^2​

Answer»

ong>Step-by-step EXPLANATION:

(a-2b)² - 2(a-2b)(2a-b)+(2a-b)²

Let a-2b=x and 2a-b=y

x²-2xy+y²=(x-y)²

Here x=a-2b and y=2a-b

(x-y)²=(a-2b-(2a-b))²

=(a-2b-2a+b)²

=(-a-b)²

=(-1)²(a+b)²

=(a+b)²

So,

(a-2b)² -2(a-2b)(2a-b)+(2a-b)²=(a+b)²

Find the positive square root of 4 x 2⅘+ 12 x 2⅗+ 37 x 2⅖ + 42 x 2⅕ + 49. full explanation i will make you brainlliest​

Answer»

ution:-

LET \sf{x=\sqrt[5]{2} }.

Then \sf{4x^4+12x^3+37x^2+42x+49} will have a square root.

Let the square root be \sf{2x^2+ax+b}.

After squaring, it needs to equal to the above.

\sf{\to{(2x^2+ax+b)^2=4x^4+12x^3+37x^2+42x+49}}

Let's apply POLYNOMIAL expansion here.

\sf{\to{4x^4+a^2x^2+b^2+2(2ax^3+abx+2bx^2)}}

\sf{\to{4x^4+4ax^3+a^2x^2+4bx^2+2abx+b^2}}

Comparing the COEFFICIENTS

  • \sf{4ax^3=12x^3} [a=3]
  • \sf{2\times3\times bx=42x} [b=7]

Therefore, it is a COMPLETE square.

\sf{(2x^2+3x+7)^2}

After substituting the value

\sf{2\times 2^\frac{2}{5} +3\times 2^\frac{1}{5} +7} is the positive value.

Answer»

Question

⠀⠀⠀⠀• The sum of first two angles of a triangle is ⠀⠀⠀⠀⠀108° and the sum of the last two angles is

⠀⠀⠀⠀⠀132º Find the angles.

Answer

⠀⠀⠀⠀⠀•∠A= 48°

⠀⠀⠀⠀⠀• ∠B= 60°

⠀⠀⠀⠀⠀• ∠C = 72°

Given

⠀⠀⠀⠀• Sum of first two angles is 108°

⠀⠀⠀⠀• Sum of last two angles is 132°

To Calculate

⠀⠀⠀⠀• Angles __?

STEP by step explanation

⠀⠀⠀⠀⠀

Let The angles of TRIANGLES be A,B,C

A+B+C = 180° ( {\sf{\red{Angle\: Sum \: Property}}} )

∠A+∠B= 108° ( {\sf{\red{Given}}} )

Putting,

➫ 108° + ∠C = 180°

➫ ∠C= 180° - 108°

{\boxed{\blue{\tt{➫∠C= 72° }}}} ______________(1)

∠B+∠C= 132°

Putting value of C from eq 1

➫∠B+72°=132

➫ ∠B = 132-72

{\boxed{\blue{\tt{➫ ∠B= 60°}}}} ______________(2)

∠A+∠B= 108°( {\sf{\red{Given}}} )

Putting value of B from eq 2

➫ ∠A+60°= 108°

➫ ∠A = 108°-60°

{\boxed{\blue{\tt{➫∠ A= 48°}}}}

{\huge{\underline{\underline{\sf{\blue{Hence :-}}}}}}

⠀⠀⠀⠀⠀•∠A= 48°

⠀⠀⠀⠀⠀• ∠B= 60°

⠀⠀⠀⠀⠀• ∠C = 72°
