solvefor x,2xsquared+14x-21=0

solve for

x, 2 x s q u a re d + 14 x - 21 = 0

x = \frac{21}{2 ( e a d sr q u + 7 )}; a \neq = - \frac{7}{e d s q u r}

Solution steps

2 x s q u a re d + 14 x - 21 = 0

Move

21

to the right side

2 x s q u a re d + 14 x = 21

Factor

2 x s q u a re d + 14 x : 2 x (e a d sr q u + 7)

2 x (e a d sr q u + 7) = 21

Divide both sides by

2 (e a d sr q u + 7); a \neq = - \frac{7}{e d s q u r}

x = \frac{21}{2 ( e a d sr q u + 7 )}; a \neq = - \frac{7}{e d s q u r}

0 = 1 - x

(10 - 1) (c^{12}) = 0

h, c = \frac{a + b}{2} \cdot h

x - 3 = 2 x + 5

\frac{x}{3} + 5 = 11
