Question

PLEASE HELP!

Answer 1

$3x^2 + 23x - 8$ can be factored into $(3x - 1)(x + 8)$. To double-check, you can multiply the terms together again using FOIL: first, outside, inside, last.

(3x)(x) + (3x)(8) + (-1)(x) + (-1)(8)

3x² + 24x - x - 8

3x² + 23x - 8

Check.

Answer 2

Answer:

Option (d) is correct.

The factored form of given quadratic equation $3x^2+23x-8$ is $(3x-1)(x+8)$

Step-by-step explanation:

Given :equation $3x^2+23x-8$

We have to factorize the given quadratic equation.

Consider the given quadratic equation $3x^2+23x-8$

we can factorize the given quadratic equation using middle term splitting method,

split middle term in such a way that the middle term becomes the product of two other terms.

23x can be written as 24x-x

equation becomes,

$3x^2+23x-8$

$\Rightarrow 3x^2+24x-x-8$

Taking 3x common from first two terms and -1 common from last two terms , we get,

$\Rightarrow 3x(x+8)-1(x+8)$

$\Rightarrow (3x-1)(x+8)$

Thus, The factored form of given quadratic equation $3x^2+23x-8$ is $(3x-1)(x+8)$
