If 2x^2+5x-12 = (2x-3)(x+4), which equation(s) should be solved to find the roots of 2x^2+5x-12=0? Check all that apply.
Fynjy0 [20]

ANSWER

2x-3=0

and

x+4=0

EXPLANATION

Given that:

2 {x}^{2}  + 5x - 12 = (2x - 3)(x + 4)

Then to find roots of

2 {x}^{2}  + 5x - 12 = 0

is the same as finding the roots of

(2x - 3)(x + 4) = 0

By the zero product property, we must have either,

2x - 3 = 0 \: or \: x + 4 = 0

Hence the equations that must be solved to find the roots are:

2x-3=0

and

x+4=0

Solve for m.<br><br> -5m = -35<br> m = <br> please exsplain your answer theroly
andrew-mc [135]
Simple,

so you have...

-5m=-35

You are trying to find m, so, to isolate the variable divide both sides by -5:

\frac{-5m}{-5} = \frac{-35}{-5}

m=7

Now, to check your work, plug in m.

-5(7)=-35

-35=-35

Thus, you know your answer is correct.
