Question

Find the product of (5-2x) (3+x)

Answer 1

Step-by-step explanation:

$(5 - 2x)(3 + x) \\ = 15 + 5x - 6x - 2 {x}^{2} \\ = 15 - x - 2 {x}^{2}$

Answer 2

Answer:

$(5 - 2x) (3 + x)$

Step-by-step explanation:

$5(3 + x) - 2x(3 + x)$

$15 + 5x - 6x - 2x {}^{2}$

$- 2x {}^{2} - x + 15$

$- 2x {}^{2} - 6x + 5x + 15$

$- 2x(x + 3) + 5(x + 3)$

$(- 2x + 5)(x + 3)$

$- 2x + 5 = 0$

$2x = 5$

$x = 5 \div 2 = 2.5$

other answer two answer this question having

$x + 3 = 0$

$x = 3$
