Solve this equation and pick the correct answer
2x^2+5x-7=0
1. x = 7 and x = -2
2. x = -7/2 and x = 1
3. x = -7 and x = 2
4. x = 7/2 and x = -1
i have summer homework and i do not understand this question an anyone explain it to me.

2.  x = -7/2 and x = 1.

Step-by-step explanation:

2x^2 + 5x - 7 = 0

(2x + 7)(x - 1) = 0

x = -7/2, 1.

The answer is 2) x = -7/2 and x = 1

Step-by-step explanation:

You have to use the a•c method.

a^2+b+c

a = 2

b = 5

c = -7

Multiply a(b) = 2(-7)

That'll equal -14. Then find factors of -14 that, when added, will equal to 5 (which is the 'b').

The factors are 7, -2.

Break up the 5x in the equation to -2x and 7x.

It looks like this: 2x^2-2x+7x-7=0

Then group them into two separate groups with parentheses.

It looks like this: (2x^2-2x) + (7x-7)

Then take out the GCF (Greatest Common Factor) for each of the groups.

Like this: 2x(x-1) + 7(x-1)

Then group the 2x and 7 together and only use one of the (x-1).

Like this: (2x+7)(x-1)

Then solve each parentheses by making both equal to zero separately.

Like this: 2x+7 = 0, x-1 = 0

Then solve each one of them for x.

2x+7 = 0

-7 -7

2x = -7

2x/2 = -7/2

x = -7/2

x-1 = 0

+1 +1

x = 1

Then you have your answers: x = -7/2 and x = 1

i'm not sure what you mean but in todays world there is a lot of women that are the bread winners in the family. there is a lot more single mothers now that are going back to get an education which is boosting the economy. i believe there has been a boost in the economy due to women the cosmetic industry is boosting, chemist, the sky is becoming the limit for women in todays economy. most women are also putting off having kids just to make sure they have a education. i don't know how these two relate though to scriptures because it's not the way the lord wanted it. the man is suppose to be the bread winner and due to social media and the easy access we have there is a lot of cheating going on.
