Someone help ASAP solve -5x^2+7x=-9

Ray Of Light [21]

Answer:

$x=\frac{7 +/-\sqrt{229} }{10}$

Step-by-step explanation:

To solve the quadratic, use inverse operations to set it equal to 0.

$-5x^2+7x=-9\\-5x^2+7x+9=0$

To solve, use the quadratic formula and substitute a= -5, b= 7 and c= 9.

$x=\frac{-b +/-\sqrt{b^2-4ac} }{2a} \\\\x=\frac{-7 +/-\sqrt{7^2-4(-5)(9)} }{2(-5)} \\\\x=\frac{-7 +/-\sqrt{49+180} }{-10} \\\\x=\frac{7 +/-\sqrt{229} }{10}$
