Question

help pls

factorize 4x^2 – 16x + 7​

Answer 1

Answer:

(2x - 7)(2x - 1)

Step-by-step explanation:

$= 4 {x}^{2} - 16x + 7 \\ = 4 {x}^{2} - (14 + 2)x + 7 \\ = 4{x}^{2} - 14x - 2x + 7 \\ = 2x(2x - 7) - 1(2x - 7) \\ = (2x - 7)(2x - 1)$

Answer 2

Answer:

=4x

2

−16x+7

=4x

2

−(14+2)x+7

=4x

2

−14x−2x+7

=2x(2x−7)−1(2x−7)

=(2x−7)(2x−1)
