Question

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

Answer 1

$(5 - 2x)(3 + x) \\ 15 + 5x - 6x - 2x^{2} \\ - 2x ^{2} - x + 15 - - - \times - 1 \: \: (to \: do \: first \: numbe \: in \: positve) \\ 2x ^{2} + x - 15 \\ \\ pls..mark \: me \: as \: brainleist$

Answer 2

Answer:

Suppose (x+y) and (a+b) are two binomials.

By using the distributive law of multiplication over addition twice, to find their product as given below:

$(x+y)(a+b) = xa+xb+ya+yb$

Follow the same process in the given expression: (5-2x)(3+x)

then;

We can write (5-2x)(3+x) as:

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

                  =$15-x-2x^2$

Therefore, the product of  (5-2x)(3+x) is, $15-x-2x^2$ .
