Question

Solve the simultaneous equations
y = 2x^2
y = 3x + 14

Answer 1

x = -2

And, x = 7 ÷ 2

Explanation:

Given that

y = 2x^2

y = 3x + 14

Now equate these two above equations

2x^2 = 3x + 14

2x^2 - 3x - 14

2x^2 -7x + 4x - 14

x(2x - 7) + 2(2x - 7)

(x + 2) (2x - 7)

So it can be x = -2

And, x = 7 ÷ 2
