The answer is: x^2 -16
The equation 4x + 5 = 2 has the solution 4x = -3 and x = - 3/4 (minus 3/4).
x= Negative 4
4x - 7 = 5 + 7x x = -4
minus 1
4x + 20
x^2-4x/x^2-6x+8 = x(x-4)/(x-2)(x-4) = x/(x-2)
x(4x-2)
4x2+4x-8 4(x2+x-2) and (4x+8)(x-1)
2xy - 4x plus 8y - 16 equals x plus 4 in parentheses multiplied by 2y minus 4 in parentheses. So, the factors are ( x + 4) and ( 2y - 4) .
3/4x - 4 = 7 + 1/2x 3/4x = 11 + 2/4x 1/4x = 11 x = 44
x - 2
Let the unknown number be X: -4x-10 = 2 -4x = 2+10 -4x = 12 x = -3 Remember that a minus multiplied by a minus is equal to a plus: -4*-3 = 12
