Which equation could be used to solve y 2+7y=18 by factoring?

Answers

Answer 1

Answer:

For this case we have the following equation:

$y ^ 2 + 7y = 18$

Rewriting the equation we have:

$y ^ 2 + 7y-18 = 0$

Then, we must factor the equation:

We are looking for two numbers that are equal to 7 and multiplied equal to -18.

We have then:

$(y + 9) (y-2) = 0$

Answer:

An equation that could be used to solve $y^2 + 7y = 18$ by factoring is:

$(y + 9) (y-2) = 0$

Answer 2

Answer: (y + 9)(y - 2) = 0 would be the correct answer .

Answers

$(1)/(4)$ b - 10 = 7
Take 10 to the other side.

$(1)/(4)$ b = 17

Multiply by 4 to isolate b
$(1)/(4)$ b × 4 = 17 × 4

4 and 4 cancels out

b = 68
