(b) 2x2 - 8x + 5 = 0
plzzzzzzzzzzzzzzzzzzzzzzz solve it guyz...........!!​

Answer 1

9x is the answerof this question

bec

4-8x+5=0

4x+5=0

9x=0

Answer 2

simplify both sides of the equation.

$2 \times 2 - 8x + 5 = 0 \\ 4 + - 8x + 5 = 0$

$( - 8x) + (4 + 5) = 0 \: \: (combine \: like \: terms) \\ - 8x + 9 = 0$

$- 8x + 9 = 0$

subtract 9 from both sides.

$- 8x + 9 - 9 = 0 - 9 \\ - 8x = - 9$

Divide both sides by -8.

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

$x = \frac{9}{8}$
