Question

Find the product: (i) (5 – 2x) (3 + x)​

Answer 1

Solution:

$\:$

$\large\red{ \longrightarrow} \pmb{ \sf{(5 – 2x) (3 + x)}}$

$\:$

$\mapsto \: \: \: \sf{5(3 + x) – 2x(3 + x)}$

$\:$

$\mapsto \: \: \: \sf{(5 × 3) + (5 × x) – (2x × 3) – (2x × x)}$

$\:$

$\leadsto \: \: \: \sf{ 15 + 5x – 6x – 2x ^{2} }$

$\:$

hope it helps!! :)

Answer 2

(5 - 2x)(3 + x)
5(3 + x) -2x(3 + x)
15 + 5x -6x - 2(x^2)
-2(x^2) - x + 15
