Consider the quadratic equation x2 + 2x - 35 = 0. Solve by factoring and using the zero-product property.
Morgarella [4.7K]

Answer:

x = -7

x = 5

Step-by-step explanation:

The standard form of quadratic equations is

Ax^2 + Bx + C = 0

The factors need to multiply together to be C and add together to be B.

The two numbers that will multiply together to be -35 and add together to be 2 are -5 & 7.

The factor pairs are (x+7)(x-5). Zero product property means we set each of those factor pairs = 0 and solve.

x + 7 = 0

-7 -7 Subtract 7 from each side to solve

x = -7

x - 5 = 0

+5 +5 Add 5 to each side to solve

x = 5

For each boat he sells, Mick earns $149 in
zavuch27 [327]

Answer: c = 149 + 0.02p

Step-by-step explanation:

From the question,

P = purchase price of the boat

C = Mick's commission

From the scenario in the question, the commission earned by Mick will be:

c = 149 + (2% × p)

c = 149 + (0.02p)

c = 149 + 0.02p

Rewrite the quadratic function in intercept or factored form<br><br> g(m)=3m^2+5-8m
gogolik [260]

Split the second term in 3m^2 + 5 - 8m into two terms

3m^2 - 3m - 5m + 5

Factor out the common terms in the first two terms, then in the last two terms.

3m(m - 1) - 5(m - 1)

Factor out the common term m - 1

<u>(m - 1)(3m - 5)</u>
