Question

Using the identity factorise the
following a²+2ab+b²=(a+b)²
(1) x² + 4x + 4
(2) 9x²+30x+25​

Answer 1

Answer:

(297)(303)

=(300−3)(300+3)

Using ,

(a−b)(a+b)=a2−b2 we get,

(300)2−(3)2

=90000−9

=89991

1) Product = 4 and Sum = 4
x^2 + 2x + 2x + 4
x (x+2) + 2(x+2)
(x+2)(x+2)

2) Product = 225 and Sum = 30
9x^2 + 15x + 15x + 25
3x (3x+5) + 5(3x+5)
(3x+5)(3x+5)
