3 0

Answer:

56q2 - 10q

Step-by-step explanation:

1. the function is given h(x) = 7x + 4q

2. we should put (8q2 - 2q) instead of x

3. we should write when x = 8q2 - 2q

then it will be h(8q2 - 2q)= 7(8q2 - 2q) + 4q

4. then we should multiply the elements in the bracket with 7 then it will be 56q2 - 14q + 4q

5. then we should substract -14q + 4q then it will be -10

6. and answer comes 56q2 - 10q

Solve using quadratic equations
olasank [31]
4x² - 9x² + 5 = 0
4x² - 4x - 5x + 5 = 0
4x(x - 1) - 5(x - 1) = 0
(4x - 5)(x - 1) = 0

Set each binomial equal to zero. 

4x - 5 = 0
4x = 0 + 5
4x = 5
x = 5/4

x - 1 = 0
x = 0 + 1
x = 1

Your solutions are x = 1, 5/4
