Multiply.
DanielleElmas [232]

Answer & Step-by-step explanation:

<em>(x² - 5x)(2x² + x - 3)</em>

Multiply each term from the first expression into the second expression.

<em>2x⁴ + x³ - 3x² - 10x³ - 5x² + 15x</em>

Combine like terms.

<em>2x⁴ - 9x³ - 8x² + 15x</em>

So, after you multiply the expressions, your answer will be 2x⁴-9x³-8x²+15x.

Which of the following best describes the graph of this system of equations ? y=-2x+3 and 5y=-10x +15
ELEN [110]

Remark

When talking about straight lines, D is never true. Never.

C is possible, but in this case not true. Read on.

B. Might be true but in this case it is not. The lines (to be parallel) have to have the same number in front of the x. These two lines do when you divide through by 5. But the y intercept has to be different. That is not so in this case. So B is incorrect.

A is your answer. If you divide through by 5 on the second one, you get the first one. They are identical.
