$(5-2x)(3+x)$
✓
Answer
$(5-2 x)(3+x)$
$=(5) \times(3+x)-(2 x) \times(3+x) $
$ =(5 \times 3)+(5 \times x)-(2 x \times 3)-(2 x \times x) $
$ =15+5 x-6 x-2 x^2 $
$ =15-x-2 x^2 \quad \text {[adding like terms]}$
$=(5) \times(3+x)-(2 x) \times(3+x) $
$ =(5 \times 3)+(5 \times x)-(2 x \times 3)-(2 x \times x) $
$ =15+5 x-6 x-2 x^2 $
$ =15-x-2 x^2 \quad \text {[adding like terms]}$
