Question

Factorize: 4x^2-35x-9

Answer 1

Answer:

${4x}^{2} - x + 36x - 9 \\ = x(4x - 1) + 9(4x - 1) \\ = (4x - 1)(x + 9) \\ = > (4x - 1) = 0 \: \: or = > x + 9 = 0 \\ = > x = \frac{1}{4} \: or \: x = - 9 \\ = > x = \frac{1}{4} \\ hope \: it \: will \: help \: you$

Answer 2

4x² - 35x - 9

= 4x² - 36x + x - 9

= 4x(x - 9) + 1(x - 9)

= (x - 9)(4x + 1).
