2x^2-7x-9=6 solve my factoring but cannot factor by grouping

x = - , x = 5

Step-by-step explanation:

Given

2x² - 7x - 9 = 6 ( subtract 6 from both sides )

2x² - 7x - 15 = 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 × - 15 = - 30 and sum = - 7

The factors are - 10 and + 3

Use these factors to split the x- term

2x² - 10x + 3x - 15 = 0 ( factor the first/second and third/fourth terms )

2x(x - 5) + 3(x - 5) = 0 ← factor out (x - 5) from each term

(x - 5)(2x + 3) = 0

Equate each factor to zero and solve for x

2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = -

x - 5 = 0 ⇒ x = 5

answer: huh

step-by-step explanation:

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
