-3x^2(6x^2 + 2x - 3) = -18x^4 - 6x^3 + 9x^2

we have

$-3x^{2} (6x^{2}+2x-3)$

solve the multiplication

$-3x^{2} (6x^{2}+2x-3)=(-3x^{2}*6x^{2})-(3x^{2}*2x)+(3x^{2}*3)\\=-18x^{4} -6x^{3}+9x^{2}$

therefore

<u>the answer is</u>

$-18x^{4} -6x^{3}+9x^{2}$

Find the value of a and of b for which<br>(a) the solution of x2 + ax < b is<br>-2<x < 4

KengaRu [80]

Answer: $a = -2$

$b = 8$

Step-by-step explanation:

Given :

$x^{2} +ax$

re - writing the equation , we have

$x^{2} +ax-b$

we need to find the value of a and b for which -2<x < 4 , this means that the roots of the quadratic equation are -2<x < 4.

The formula for finding the quadratic equation when the roots are known is :

$x^{2}$ - sum of roots(x) + product of root = 0

sum of roots = -2 + 4 = 2

product of roots = -2 x 4 = -8

substituting into the formula , we have:

$x^{2} -2x-8=0$ , which could be written in inequality form as

$x^{2} -2x-8$

comparing with $x^{2} +ax-b$ , it means that :

$a = -2$

$b = 8$
