(x + 11)(x - 4)
49/4 or 12.25
I'll show work. X2-8x-4=0. X2-8x=4. X-8x=2. -7x=2. X=-(2/7).

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.
Did you get the question from sevenstar academy, Algebra.
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]}
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
x2-7x+12 (x-3)(x-4)
x2+7x-44 = (x-4)(x+11) when factored
x2-7x-44 = (x+4)(x-11) when factored
Do you mean x2+7x+12? If so then it is: (x+3)(x+4)
-3
=3x * * * * * The correct answer is: x2 + 7x + 12 = (x + 3)(x + 4).
7x 2= 14
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
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.
