Question
Which expression is equivalent to 5x2 – 18x + 9?
O (5x - 1)(x – 9)
O (5x – 9)(x + 1)
O (5x – 3)(x - 3)
O (5x + 3)(x - 3)

Answer 1

Answer:

(5x – 3)(x - 3)

Step-by-step explanation:

Break the expression into groups

$=\left(5x^2-3x\right)+\left(-15x+9\right)$

Factor out

$=x\left(5x-3\right)-3\left(5x-3\right)$

Factor out common terms

$=\left(5x-3\right)\left(x-3\right)$

Hence, Answer is (5x-3)(x-3)
