Answer:

[tex]\boxed {\boxed {\sf (x+2)(x-5)}}[/tex]

Step-by-step explanation:

To factor by grouping, first divide the polynomial into 2 groups with parentheses.

[tex]x^2-5x+2x-10[/tex]

[tex](x^2-5x)+ (2x-10)[/tex]

Factor the greatest common factor (GCF) out of both binomials.

For the first binomial, the GCF is x.

[tex]x(x-5) +(2x-10)[/tex]

For the second binomial, the GCF is 2.

[tex]x(x-5)+2(x-5)[/tex]

Factor out the common binomial which is (x-5).

[tex](x+2)(x-5)[/tex]

The factorized form of x²-5x+2x-10 is (x+2)(x-5)
