Question

1 Multiply the binomials. (i) (2x + 5) and (4x - 3) (ü) (y - 8) and (3y - 4) (ii) (2.51 -0.5m) and (2.51 + 0.5m) (iv) (a + 3b) and (x + 5) (v) (2pq + 3q?) and (3pq - 292) a2 ? 4 - (vi) ( a + 3b") and 4 (a b) ? - Find the product. (i) (5-2x) (3 + x) (ii) (x + 7y) (7x - y) (iii) (a? + b)(a + b) (iv) (p- q?) (2p+q) Simplify: (i) (x2 - 5) (x + 5) + 25 (i) (a? + 5) (b3 + 3) + 5 (iii) (t + s?) (t? - s) (iv) (a + b) (c)d) + (a - b) (c + d) +2 (ac + bd) (v) (x + y) (2x + y) + (x + 2y) (x - y) (vi) (x + y) (x2 - xy + y2) (vii) (1.5x - 4y) (1.5x + 4y + 3) - 4.5x +12y (viii) (a + b + c)(a + b - c) C -​

Answer 1

Answer:

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

8x2 -6x +20x -15

8x2 + 14x -15

ii y(3y-4)-8(3y -4)

3y2 -4y -24y +32

3y2 - 28y +32

a(x+5)3b (x+5)

ax +5a +3bx +15b
