Question

Simplify (5x – 3) (x+4) - (2x + 5) (2x - 1)​

Answer 1

Question :-

• Simplify (5x – 3) (x+4) - (2x + 5) (2x - 1)

Solution :-

• Let's simplify step-by-step.

(5x−3)(x+4)−(2x+5)(2x−1)

• Distribute:

=(5x)(x)+(5x)(4)+(−3)(x)+(−3)(4)+−4x2+−8x+5

=5x^2+20x+−3x+−12+−4x^2+−8x+5

• Combine Like Terms:

=5x^2+20x+−3x+−12+−4x^2+−8x+5

=(5x^2+−4x^2)+(20x+−3x+−8x)+(−12+5)

=x^2+9x+−7

Answer :- x^2+9x+−7
