Do you mean the following?
x2 = 4 - 7x
If so, then:
x2 + 7x = 4
x2 + 7x + 49/4 = 4 + 49/4
(x + 7/2)2 = 65/4
x + 7/2 = ±√65 / 2
x = (-7 ± √65) / 2
So x is equal to (-7 - √65) / 2 and (-7 + √65) / 2

What is x2 7x 12 factored?
As I cannot see the marks in between, I will do it for all possibilities.x^2+7x+12:(x+4)(x+3)_________________________________________________________________x^2-7x+12:(x-4)(x-3)The other two possibilities do not have real values, so I have excluded them.
What are the exact solutions of x2 equals 4 minus 7x?
Did you get the question from sevenstar academy, Algebra.
What are the exact solutions of x2 equals 4 - 7x?
x2 = 4 - 7x x2 + 7x - 4 = 0 Using the quadratic formula, x = 1/2*{-7 ± sqrt[72 - 4*1*(-4)]} = 1/2*{-7 ± sqrt[49 + 16]} = 1/2*{-7 ± sqrt[65]}
How many solutions does the equation X 2 plus 7X plus 12 have?
None because without an equal it is not an equation. But if it was in the form of x2+7x+12 = 0 then it would have 2 solutions which are x = -3 and x = -4

Twelve more than the square of number is seven times number Find the number?
Suppose the number is x. Then x2 + 12 = 7x So that x2 - 7x + 12 = 0 ie (x - 3)(x - 4) = 0 So the two possible solutions are x = 3 and x = 4
What is the equiation for x2 7x44?
That is the equation, or would be if the signs were shown. The factors are (x - 11)(x + 4) which is equivalent to x2 - 7x - 44 or (x + 11)(x - 4) which is equivalent to x2 + 7x - 44.
