Answer:
14, 19, 26, 7
Step-by-step explanation:
f(3) = 2(3)^2 - 3(3) + 5
f(3) = 2(9) - 9 + 5
f(3) = 18-9+5
f(3) = 14
f(-2) = 2(-2)^2 - 3(-2) + 5
f(-2) = 2(4) + 6 + 5
f(-2) = 8 + 6 + 5
f(-2) = 19
g(10) = 3(10) - 4
g(10) = 30-4
g(10) = 26
17 = 3x-4
21 = 3x
7 = x

Answer:
x=3/2, x=-4
Step-by-step explanation:
2x^2 + 5x - 12
First lets see if we can factor this
(2x ) ( x )
-12 = -1*12 1*-12
- 2*6 2 * -12
- 3*4 3 * -4
2 * one of these pairs - the other pair = +5
2*4 -3 = 5
Put the -3 in the first spot and the 4 in the second spot
(2x-3) ( x+4)
Using the zero product property
2x-3 =0 x+4=0
2x=3 x=-4
x = 3/2
