Answer 1

Answer

Step-by-step explanation:

10$x^{2}$+3x- 4x

10$x^{2}$ + 8x- 5x-4 = 0

5x(2x-1) + 4(2x-1)

(5x+4)(2x-1)

hope it helps you!!

Answer 2

$\huge\underline\pink{FàçtoRísàtíöñ}$

10x² + 3x - 4

10x² + 8x - 5x - 4

2x(5x+4) -1(5x+4)

(2x-1) (5x+4)

x = 1/2 x ≠ -4/5

Therefore ,

x = 1/2
