Question

$4x^{2} - 16x + 7$
​

Answer 1

Step-by-step explanation:

4x² - 16x + 7

4x² - (14+2)x +7

4x²- 14x - 2x + 7

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

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

Answer 2

Given:

$4x^{2} - 16x + 7$

To find:

the solution

STEP BY STEP EXPLANATION:

$4x^{2} - 16x + 7$

write -16 x as a difference

$4 {x}^{2} - 2x - 14x + 7$

factor out 2 x from the expression

$2x \times (2x - 1) - 14x + 7$

$4 {x}^{2} - 2x - 14x + 7$

factor out -7 from the expression

$2x \times (2x - 1) - 7(2x - 1)$

factor out 2 x -1 from the expression

$(2x - 1) \times (2x - 7)$
