Question

What is the positive solution to this equation?
4x²+12x=135

Answer 1

4x^2 + 12x - 135 =0
Using calculator mode 3 3 or formula
X= 9/2 or x = -15/2

Answer 2

x = 4.5

Explanation:

Solve for x by using the quadratic formula

x = -12 + or -
`√(144+2160)` / 8

so (-12 + 48) / 8 or (-12 - 48) / 8

so 36/8 or -60/8, they just want the positive solution so x = 4.5
