Question

Solve for all values of x by factoring.
x^2−9x+3=3

Answer 1

SolutioN:-

`\sf \longrightarrow \: {x}^(2) - 9x + 3 = 3`

`\sf \longrightarrow \: {x}^(2) - 9x + 3 - 3 = 0`

`\sf \longrightarrow \: {x}^(2) - 9x + 0 = 0`

`\sf \longrightarrow \: {x}^(2) - 9x = 0`

`\sf \longrightarrow \: x(x - 9) = 0`

`\sf \longrightarrow \: x(x - 9) = 0`

`\sf \longrightarrow \: x = 0 \qquad \: and \: \qquad x-9 =0`

`\sf \longrightarrow \: x = 0 \qquad \: and \: \qquad x =0+9`

`\sf \longrightarrow \: x = 0 \qquad \: and \: \qquad x =9`
