![2{x}^{2} + 7x - 4](/tpl/images/0360/9472/58ede.png)
Step-by-step explanation:
F [First terms] - Multiply the first terms in each set of parentheses FARTHEST TO THE LEFT
O [Outside terms] - Multiply the first term in the first set of parentheses FARTHEST TO THE LEFT by the last term in the second set of parentheses FARTHEST TO THE RIGHT
I [Inside terms] - Multiply the last term in the first set of parentheses FARTHEST TO THE RIGHT by the first term in the second set of parentheses FARTHEST TO THE LEFT
L [Last terms] - Multiply the last terms in each set of parentheses FARTHEST TO THE RIGHT
![(2x - 1)(x + 4) = 2{x}^{2} + 8x - x - 4 = 2{x}^{2} + 7x - 4](/tpl/images/0360/9472/30e24.png)
I am joyous to assist you anytime.
