pls show work and how to do it! thank you!!!!!

Answer 1

Move all terms to the left side of the equation and simplify.

4x²+7x−2=0

Use the quadratic formula to find the solutions.

(−b±√b2−4(ac))/2a Substitute the values a=4 , b=7, and c=−2 into the quadratic formula and solve for x.

(−7±√72−4⋅(4⋅−2))/2⋅4 Simplify.

x=−(7±9)/8 .The final answer is the combination of both solutions.

x=1/4,−2
