(X+2)(4x-3) multiply place in descending powers
VMariaS [17]

Multiplying out the equation (x + 2)(4x - 3) and arranging in descending powers order gives us the quadratic form as; 4x² + 5x - 6

<h3>How to expand quadratic equations?</h3>

(x + 2)(4x - 3)

Multiplying out gives us;

4x² + 8x - 3x - 6

⇒ 4x² + 5x - 6

Thus, we can conclude that multiplying out the equation (x + 2)(4x - 3) and arranging in descending powers order gives us the quadratic form as; 4x² + 5x - 6
