Question

Can someone help me with factoring by grouping

please show step by step

problem: x^2+3x-10

Answer 1

Factor : x^2+3x-10

Answer = (x - 2)(x + 5)

Step-by-step explanation:

Y = x^2 + 3x - 10.

Find 2 numbers knowing sum (3) and product (-10).

Factor pairs of (-10) -> (-1, 10)(-2, 5). This sum is 3 = b. The 2 numbers are: -2 and 5.

y = (x - 2)(x + 5).
