Question

Foctorise 2x^2-15x+22

Answer 1

Answer:

Simplifying

2x2 + -15x + 22 = 0

Reorder the terms:

22 + -15x + 2x2 = 0

Solving

22 + -15x + 2x2 = 0

Solving for variable 'x'.

Factor a trinomial.

(2 + -1x)(11 + -2x) = 0

Subproblem 1

Set the factor '(2 + -1x)' equal to zero and attempt to solve:

Simplifying

2 + -1x = 0

Solving

2 + -1x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-2' to each side of the equation.

2 + -2 + -1x = 0 + -2

Combine like terms: 2 + -2 = 0

0 + -1x = 0 + -2

-1x = 0 + -2

Combine like terms: 0 + -2 = -2

-1x = -2

Divide each side by '-1'.

x = 2

Simplifying

x = 2
