1.	If the square of the difference of zeros of the quadratic polynomial f(x) = x^2 + px + 45 is equal to 144 find the value of p.pls ans asapits urgent
Answer» <P>ANSWER: D=b^2-4ac =p (p)^2-4(1)(45) p^2-180=144 p^2=144+180 p^2=324 p= $\sqrt{324}$ p=18

If the square of the difference of zeros of the quadratic polynomial f(x) = x^2 + px + 45 is equal to 144 find the value of p.pls ans asapits urgent

Answer»

<P>ANSWER:

D=b^2-4ac

(p)^2-4(1)(45)

p^2-180=144

p^2=144+180

p^2=324

$\sqrt{324}$

p=18
