Question

Simplify the following expression: (5x2 + 3x + 4) - (2x2 - 6x + 3). If the final answer is written in the form Ax2 + Bx + C, what is the value of B?

Answer 1

5x^2 - 2x^2 + 3x + 6x + 4 - 3
3x^2 + 7x + 1

Answer 2

\[\left( 5x ^{2}+3x+4 \right)-\left( 2x ^{2}-6x+3 \right)\]
\[5x ^{2}+3x+4-2x ^{2}+6x-3\] combine like terms
\[3x ^{2}+9x+1\]

so the value of B is 9

Answer 3

lol confucious says its 9
