Question

Find the solution set of x^2+3x-10=0

Answer 1

X² + 3x -10 can be factored using simple grouping method as: (x-2)(x+5).

The zeros are 2 and -5.

Hope this helps and best of luck.

Answer 2

X^2 + 3x - 10 = 0

2x + 3x - 10 = 0

2x + 3x = 5x

5x -10 = 0

+10 +10

5x = 10

5x/5 = 10/5

X = 2


Checking: 2^2 + 3(2) - 10 = 0

4 + 3(2) - 10 = 0

4 + 6 - 10 = 0

10 - 10 = 0

0 = 0
