Question

Simplify (5x+4)(4x-2) - (3x+1)(2x-3)​

Answer 1

Answer:

= 14x² + 13x - 5

Step-by-step explanation:

⟹ (5x+4)(4x-2) - (3x+1)(2x-3)

Simplifying the given expression

⟹ 20x²-10x+16x-8-(3x+1)×(2x-3)

⟹ 20x²-10x+16x-8-(6x²-9x+2x-3)

Collecting like terms

⟹ 20x²-10x+16x-8-(6x²-7x-3)

Removing the brackets

⟹ 20x²-10x+16x-8-6x²+7x+3

⟹ 14x²-10x+16x-8+7x+3

⟹ 14x²+13x-8+3

⟹ 14x²+13x-5
