$63x^2+92x+32$

Multiply each number in the first set of parentheses by each number in the second set of parentheses, add the products together

$(7x+4)(9x+8)$

$7x*9x+7x*8+4*9x+4*8$

$63x^2+56x+36x+32 rarr$ Combine like terms

$63x^2+92x+32$

$63x^2 + 92x + 32$

$9x(7x + 4) +8(7x+4)$

$63x^2 + 36x + 56x + 32$

$= 63x^2 +92x + 32$
