Answer 1

Answer:

(a)x²+9x+20

x²+4x+5x+20

(x²+4x)+(5x+20)

x(x+4)+5(x+4)

(x+4)(x+5)

(b)x²-14x+13

x²-13x-x+13

(x²-13x)-(x+13)

x(x-13)-1(x-13)

(x-13)(x-1)

(c)p²+2p-15

p²+5p-3p-15

(p²+5p)-(3p-15)

p(p+5)-3(p+5)

(p+5)(p-3)

(e)m²-3m-70

m²-10m+7m-70

(m²-10m)+(7m-70)

m(m-10)+7(m-10)

(m-10)(m+7)

(f)3x²-10x+8

3x²-6x-4x+8

(3x²-6x)-(4x+8)

3x(x-2)-4(x-2)

(x-2)(3x-4)

(g)10p²+11p+3

10p²+5p+6p+3

(10p²+5p)+(6p+3)

5p(2p+1)+3(2p+1)

(2p+1)(5p+3)

(h)11a²+54a+63

11a²+33a+21a+63

(11a²+33a)+(21a+63)

11a(a+3)+21(a+3)

(a+3)(11a+21)

(i)12y²+28y-5

12y²+28y-5

12y²-2y+30y-5

(12y²-2y)+(30y-5)

2y(6y-1)+5(6y-1)

(6y-1)(2y+5)
