Question

0.25x2 -0.25x - 10.5 = 0​

Answer 1

x=7 or x=-6

Let's solve your equation step-by-step.

0.25x2−0.25x−10.5=0

For this equation: a=0.25, b=-0.25, c=-10.5

0.25x2+−0.25x+−10.5=0

Step 1: Use quadratic formula with a=0.25, b=-0.25, c=-10.5.

x=

−b±√b2−4ac

2a

x=

−(−0.25)±√(−0.25)2−4(0.25)(−10.5)

2(0.25)

x=

0.25±√10.5625

0.5

x=7,−6
