Answer: The answer is A, 40.

2 x 2 = 4 + 4 x 4 = 16

4 + 16

ASAP! what is 5x^2-18x+9????

netineya [11]

Answer:

(x - 3)(5x - 3)

Step-by-step explanation:

Assuming you require the expression to be factorised.

Given

5x² - 18x + 9

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 = 5 × 9 = 45 and sum = - 18

The factors are - 15 and - 3

Use these factors to split the x- term

5x² - 15x - 3x + 9 ( factor the first/second and third/fourth terms )

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

= (x - 3)(5x - 3) ← in factored form
