Question

(x + 1)(x + 3) + (x + 2)(x + 4)

Answer 1

Explanation:

Hello!

(x + 1)(x + 3) + (x + 2)(x + 4)

x*x = x²

x*3 = 3x

1*x = x

1*3=3

x*x=x²

x*4 = 4x

2*x= 2x

2*4 = 8

x²+3x+x+3+ x² + 4x+ 2x+ 8=

2x² + 10x+ 11

Answer 2

Explanation:

x²+3x+x+3+x²+4x+2x+8

2x²+10x+11....then solve quadratically
