Question

8. Express b in terms of a, c and P in *


b^2-4ac/p=3

Answer 1

Answer:  $\bold{b=\pm\sqrt{3p+4ac}}$

Step-by-step explanation:

$\dfrac{b^2-4ac}{p}=3\\\\\\\text{Multiply both sides by p:}\\b^2-4ac=3p\\\\\\\text{Add 4ac to both sides:}\\b^2=3p+4ac\\\\\\\text{Take the square root of both sides:}\\b=\pm\sqrt{3p+4ac}$
