## Related Questions 4x2+12x = 4x(x+3) when factored  If this is algebra then; 3x plus 12x = 15x 12x and then the squared. (the little two)   9x2...I guess that means 9x squared ? The problem: 9x(squared)+12x+4 Here's the answer: (3x+2)(3x+2) or even more simplified: (3x+2) squared I assume you mean (x+10)(x+2) This would equal x^2+12x+20 x^2 means x squared     Factor. X^2 + 12X X(X + 12) = 0 X = 0 ------------- X + 12 = 0 X = - 12 --------------  The factors of 5 are 1 and 5. 12 = 2 x 5 + 2 x 1, therefore: 4x2 +12x +5 = (2x + 1)(2x + 5) x2 + 12x + 36 = 0(x + 6) (x + 6) = 0x+ 6=0 ;x + 6 = 0x = -6 ; x = -6 it depends on what 4x-12x is equal to  It can't be factored because its discriminant is less than zero That doesn't factor neatly. Applying the quadratic equation, we find two real solutions: (-2 plus or minus the square root of 5) divided by 3x = 0.07868932583326327x = -1.4120226591665965  The constant (no x) part must be equal to the square of half the linear part, that is, (12/2)2.  3x multiplied by (12x plus 9) is:3x(12x + 9)= (3x * 12x) + (3x * 9)= 36x2 + 27x If you mean y = -12x+3 then it is a straight line equation whereas -12 is the slope and 3 is the y intercept
