Question

factorise the following polynomial y^2 + 7y + 10 ,4x^2 - 20x+ 25 9x^2 + 19x + 10 , m^2 - 10x + 25​

Answer 1

Step-by-step explanation:

a. y^2 + 7y + 10.

; y^2 + 5y + 2y + 10.

; y(y+5) + 2(y+5)

; (y+5)(y+2)

b. 4x^2 - 20x + 25.

; 4x^2 - 10x - 10x + 25.

; 2x(2x-5) - 5(2x-5).

; (2x-5)(2x-5).

c. 9x^2 + 19x + 10

; 9x^2 + 9x + 10x + 10.

; 9x(x+1) + 10(x+1).

; (x+1)(9x+10).

d. m^2 - 10m + 25.

; m^2 - 5m - 5m + 25.

; m(m-5) - 5(m-5)

; (m-5)(m-5).
