Answer» *Therefore* *the* *ANSWER* *that* *you* *REQUIRE* *will* be (*x-7)(x-3) Step-by-step explanation:* x²-10x + 21 = (x)²+[(-7)+(-3)]x + [(-7)×(-3)] x²+(a+b)x +AB = (x+a)(x+b) therefore , x²-10x + 21 [x+(-7)] [x+(-3)] = (x-7)(x-3)

Answer»

Therefore the ANSWER that you REQUIRE will be (x-7)(x-3)

Step-by-step explanation:

x²-10x + 21

= (x)²+[(-7)+(-3)]x + [(-7)×(-3)]

x²+(a+b)x +AB = (x+a)(x+b)

therefore , x²-10x + 21

[x+(-7)] [x+(-3)]

= (x-7)(x-3)
