Question

multiply the two binomials. (2x + 2)(4x - 1)=□ (simplify your answer.)

Explanation:

Step1: Use FOIL method

First terms: $(2x)\times(4x)=8x^{2}$

Step2: Outer terms

$(2x)\times(- 1)=-2x$

Step3: Inner terms

$2\times(4x) = 8x$

Step4: Last terms

$2\times(-1)=-2$

Step5: Combine like - terms

$8x^{2}-2x + 8x-2=8x^{2}+6x - 2$

Answer:

$8x^{2}+6x - 2$
