Solve the quadratic equation by completing the square.

6x^2 + 4x - 5 = 0

C

Step-by-step explanation:

6x² + 4x - 5 = 0

Quadratic formula:

b² - 4ac = 4² - 4(6)(-5) = 136

Sqrt(136) = 2sqrt(34)

[-4 +- 2sqrt(34)]/12

[-2 +- 2sqrt(34)]/6

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
