Quadratic formulat is used when a^2+bx+c=0 x= \frac{-b+/- \sqrt{b^{2}-4ac}   }{2a} 4m^2+3m-1=0 a=4 b=3 c=-1 input x= \frac{-3+/- \sqrt{3^{2}-4(4)(-1)}   }{2(4)} x= \frac{-3+/- \sqrt{9+16}   }{8} x= \frac{-3+/- \sqrt{25}   }{8} x= \frac{-3+/-5  }{8} x= \frac{-8}{8} or \frac{2}{8} x=-1 or 1/4

Is d = -4 a solution to the equation 3(d + 12) = 8 - 4d ?​
kkurt [141]
No because...

3(d+12) =8

Distribute the 3.

3d+36=8

Subtract the 36.

3d = -28

Divide by 3 to isolate d.

d = -28/3 or 9.33
