Question

Factorise the following-
2x²+3x-5
3x²-12x+12
5x²+15x+10​​

Answer 1

Answer:

2x²+3x-5

2x²+5x-2x-5

(2x²+5x)-(2x-5)

x(2x+5)-1(2x+5)

(2x+5)(x-1)

3x²-12x+12

x²-4x+4

x²-2x-2x+4

(x²-2x)-(2x+4)

x(x-2)-2(x-2)

(x-2)(x-2)

(x-2)²

5x²+15x+10

x²+3x+2

x²+x+2x+2

(x²+x)+(2x+2)

x(x+1)+2(x+1)

(x+1)(x+2)
