Answer:
20x^2−2x−6
Step-by-step explanation:
(4x+2)(5x+−3)
=(4x)(5x)+(4x)(−3)+(2)(5x)+(2)(−3)
=20x2−12x+10x−6
=20x2−2x−6
(4x + 2)(5x - 3)
Multiply:
4x(5x) = 20x^2
4x(-3) = -12x
2(5x) = 10x
2(-3) = -6
Combine Like Terms:
10x-12x = -2x
Answer:
20x^2 - 2x - 6
Multiply:
4x(5x) = 20x^2
4x(-3) = -12x
2(5x) = 10x
2(-3) = -6
Combine Like Terms:
10x-12x = -2x
Answer:
20x^2 - 2x - 6
