Question

Solve the quadratic equation x²-3x-10=0 by factorisation method.​

Answer 1

x²-3x-10=0

x²-5x+2x-10=0

x(x-5)+2(x-5)=0

(x-5)(x+2)=0

either

x-5=0

x=5

or

x+2=0

x=-2

Answer 2

x = 5 and -2

Explanation:

i hate the factorization method

The factorization method is that there are factors of c that add up to b

so -2 * 5 = -10, but so does -5 * 2, so um, i kinda forgot how to do this, but the answer is 5 and -2, I got it using m+/- √(m^2 - p)
