Question

1. Multiply the binomials.
(i) (2x + 5) and (4x3)
(iii) (2.51 -0,5m) and (2.51+0.5m)
(v) (2pq +3q?) and (3pq - 292)​

Answer 1

Step-by-step explanation:

1. (2x+5) (4x+3)

2x(4x+3) +5(4x+3)

8x^2 +6x+20x+15

8x^2 + 26x + 15.

2. (2.5l-0.5m) (2.5l+0.5m)

2.5l(2.5l+0.5m) -0.5m(2.5l+0.5)

6.25l^2 + 1.25lm - 1.25lm+0.25m

6.25l^2 -lm + 0.25m.
