What are the solutions of the quadratic equation? 4x^2+9x-9=0

vagabundo [1.1K]

Answer:

$x=3/4$

$x=-3$

Step-by-step explanation:

we have

$4x^2+9x-9=0$

we know that

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$4x^2+9x-9=0$

$a=4\\b=9\\c=-9$

substitute in the formula

$x=\frac{-9(+/-)\sqrt{9^{2}-4(4)(-9)}} {2(4)}$

$x=\frac{-9(+/-)\sqrt{225}} {8}$

$x=\frac{-9(+/-)15} {8}$

$x=\frac{-9+15} {8}=3/4$

$x=\frac{-9-15} {8}=-3$

Solve for x, worth 10 points

Anton [14]

Answer: x=22

Step-by-step explanation:

Since the angles are corresponding angles, use x+14=5x-74. You get 36=36 meaning it is right when you substitute the value for x.

x+14=5x-74

-x on both sides

14=4x-74

+74 on both sides

88=4x

Divide both sides by 4

x=22
