Answer:

B

Step-by-step explanation:

The solutions to a quadratic equation is whenever the graph crosses the x-axis. The solutions are also known as the roots or zeros of the quadratic.

Our quadratic crosses the x-axis at -3 and 1. So, at those two points, f(x) is 0. Namely, we have the two points (-3, 0) and (1, 0).

So, our two solutions are -3 and 1.

Hence, our answer is B.

Answer:

I think it would be B

Step-by-step explanation:

If f(x) is 0, that means the value of x would not change at all. and since its only on the x-axis and neither numbers are used for the y-axis, the solutions would most likely be -3 and 1.

Please help me<br> solve (x+3) (x+7)
vodka [1.7K]

Step-by-step explanation:

Here, we'll need to multiply these two values together.  I'll use the expansion formula, which goes as follows:

(a+b)(c+d)

  • Expand

ac + ad + bc + bd

Lets apply this to the following equation:

(x+3) (x+7)

  • Expand.

(x*x) + (x * 7) + (3 * x) + (3 * 7)

  • Simplify.

(x^2) + (7x) + (3x) + (21)

  • Remove parenthesis and add.

x^2+10x+21

Answer:

x^2+10x+21
