Solve for x. 2x² +21x-61 = (x+7)² Please

Ymorist [56]

Answer:

$x = \frac{-7 +\sqrt{489} }{2}$

$x = \frac{-7 - \sqrt{489} }{2}$

Step-by-step explanation:

2x² +21x-61 = (x+7)²

expand

2x² + 21x - 61 = x² + 14x +49

move everything to one side

x² + 7x - 12 = 0

use quadratic formula

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

plug in the values

$x = \frac{-7 +- \sqrt{7^{2}-4(1)(-110) } }{2(1)}$

solve

$x = \frac{-7 +- \sqrt{49-4(1)(-110) } }{2}$

$x = \frac{-7 +- \sqrt{49 + 440 } }{2}$

$x = \frac{-7 +- \sqrt{489} }{2}$

2x - 3y = 8 -2x + 6y = -20 x = ? y = ? solve the system of equations

Zolol [24]

Answer:

x = 4 + 3/2y

y = -8/3 + 2/3x

1. Finding X

2x-3y=8

2x=8+3y

x+4+3/2y

2. Finding Y

2x-3y=8

-3y=8-2x

y=-8/3+2/3x
