7x^2 + 6x - 4 = 5x^2

Write the quadratic equation in standard form.

x=−32+12√17 or x=−32+−12√17

Step-by-step explanation:

Step 1: Subtract 5x^2 from both sides.

7x2+6x−4−5x2=5x2−5x2

2x2+6x−4=0

For this equation: a=2, b=6, c=-4

2x2+6x+−4=0

Step 2: Use quadratic formula with a=2, b=6,c=-4.x=−b±√b2−4ac2ax=−(6)±√(6)2−4(2)(−4)2(2)x=−6±√684x=−32+12√17 or x=−32+−12√17
