3x^2 + 3x - 6

First factor out the 3 in front of x^2:

3( x^2 + x - 2 )

Now we can look at the inside of the brackets, and find two numbers that, when multiplied, give -2, and when added, give +1. You will usually find them if you create a list of factors of the constant term (-2 in this case).

2 * -1 = -2
2 + -1 = 1

So the factorization becomes 3(x+2)(x-1)

a)b 256What are the values of a and b in the equation(4x[4x2- ?○ a-2, b-4○ a=-2, b-4○ a-2, b=-4○ a-2, b=-422aaaa0000C日

Hi.... your answer is below:

$\left( 4.x^{a} \right)^{b}=\dfrac{256}{x^{8}}\rightarrow 4^{b}x^{ab}=256x^{-8}\rightarrow 2^{2b}.\,x^{ab}=2^{8}.\,x^{-8}\rightarrow\\ \text{by comparison}\\ 2^{2b}=2^{8}\rightarrow 2b=8\rightarrow \boxed{b=4}\\ x^{ab}=x^{-8}\rightarrow x^{4a}=x^{-8}\rightarrow 4a=-8\rightarrow \boxed{a=-2}$

Thanks....
