Question

Multiply: (2x − 3)(x2 + 4x − 3)

Answer 1

Answer: 2x^3 + 5x^2 - 18x + 9

Explanation:

Step 1:

Distribute Parentheses:

2xx^2 + 2x * 4x + 2x ( - 3 ) + ( - 3x)^2 + ( - 3 ) * 4x + ( - 3) ( - 3 )

Step 2:

Apply Minus - Plus Rules

+ ( - a) = - a

( - a ) ( - b ) = ab

2x^2 x + 2 * 4xx - 2 * 3x - 3x^2 - 3 * 4x + 3 * 3

Step 3:

Simplify:

2x^2 x + 2 * 4xx - 2 * 3x - 3x^2 - 3 * 4x + 3 * 3

Answer: 2x^3 + 5x^2 - 18x + 9

Hope that helps!
