Question

I need some help{y=2x^2+6x-10y=-x+5 I have to find the solutions to the system of equations

Answer 1

Step-by-step explanation:

First equation: y=2x²+6x-10

2nd equation: y= -x+5

since we have y in both equations, we will equate both of them together.

y = y

2x²+6x-10 = -x+5

collect like terms:

2x² + 6x + x - 10 - 5 = 0

2x²+ 7x - 15 = 0

Using factorisation method to fin the values of x:
