Question

Find the product:

(i) (5 – 2x) (3 + x)​

Answer 1

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

Answer 2

`\:`

`\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) }`
