simplify (x-8)(x+4)+(x-3)(x+9)

simplify

(x - 8) (x + 4) + (x - 3) (x + 9)

2 x^{2} + 2 x - 59

Solution steps

(x - 8) (x + 4) + (x - 3) (x + 9)

Expand

(x - 8) (x + 4) : x^{2} - 4 x - 32

= x^{2} - 4 x - 32 + (x - 3) (x + 9)

Expand

(x - 3) (x + 9) : x^{2} + 6 x - 27

= x^{2} - 4 x - 32 + x^{2} + 6 x - 27
