Answer 2

Answer:

A. $10x^{2} + 33x^{2} +19x - 12$

Explanation:

$(2x + 3) (5^{2} + 9x - 4)$

Mutiply $2x$ by each number on the second bracket

$(2x) (5^{2} ) = 10x^{3} \\(2x) (9x ) = 18x^{2} \\(2x) (- 4 } ) = -8x$

Then mutiply 3 by each number on the second bracket

$(3) (5^{2} )= 15x^{2} \\(3) (9x) = 27x\\(3) (-4) = -12$

New equation:

$10x^{3} + 18x^{2} + -8x + 15^{2} + 27x - 12$

Add all like terms

$10x^{3} + 33x^{2} + 19x - 12$
