Question

help me omg!! which expression gives the solution of: -5+2x(2)=-6x? see replies!!!

Answer 1

a. \[2\pm \sqrt{4-(4)(6)(-5)} \over 12\]

Answer 2

b. \[-5\sqrt{25-(4)(2)(6)} \over -10\]

Answer 3

c. \[-6\pm \sqrt{36-(4)(2)(-5)} \over 4\]

Answer 4

d.\[6\pm \sqrt{36-(4)(2)(-5)}\]

Answer 5

c.

Answer 6

can you explain why please? i have to show some work.

Answer 7

-5+2x^2+6x=0

\[\sqrt{-b \pm b^2 -4ac} / 2a\]

Answer 8

b=6

a=2

c=-5

Answer 9

\[2x ^{2} + 6x - 5 = 0\]

By the quadratic formula, \[x= -6 \pm \sqrt{6^{2} - (4)(2)(-5)} \div 4\]

The quadratic formula is \[x = -b \pm \sqrt{b ^{2} - 4ac} \div 2a \]

for \[ax ^{2} + bx + c =0\]
