Answer:
-14
Step-by-step explanation:
Okay first we must simplify the expression.
so this:(3x^2 + x-2)(x - 5)
becomes this:3x^3-14x^2-7x+10
then we look at the coefficient of x^2 and we see that it's -14
I think it’s (-1,-4) sorry if it’s wrong
This is how you solve it.
4x = 2/5 is the same equation
Multiply 1/4 on both sides to clear the 4.
x = (2/5)(1/4) =2/20= 1/10
CHECK
(1/10)* 4= 4/10 = 2/5
