Step-by-step explanation:
Given
2x² + x - 1 = 2 ( subtract 2 from both sides )
2x² + x - 3 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × - 3 = - 6 and sum = + 1
The factors are - 2 and + 3
Use these factors to split the x- term
2x² - 2x + 3x - 3 = 0 ( factor the first/second and third/fourth terms )
2x(x - 1) + 3(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(2x + 3) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = -

Answer:
a) find the value of y when x is equal to 4.
Step-by-step explanation:
Substitute -8 for t in <span>h(t)=-2(t+5)^2+4:
h(-8) = -2(-8+5)^2 + 4 = -2(-3)^2 + 4 = -2(9) + 4 = -18 + 4
h(-8) = -18 + 4 = -14 (answer)</span>
