Question

Simplify (1.5x-4)(1.5x+3)-4.5x+12 with all steps

Answer 1

Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd(a+b)(c+d)=ac+ad+bc+bd.

2.25{x}^{2}+4.5x-6x-12-4.5x+122.25x

2+4.5x−6x−12−4.5x+1

Collect like terms.

2.25{x}^{2}+(4.5x-6x-4.5x)+(-12+12)2.25x

2+(4.5x−6x−4.5x)+(−12+12)

Simplify.

2.25{x}^{2}-6x2.25x

2−6x

Done
