Question

-x^2+7x-10=0 by quadratic formula grade 10first to answer​ will get brainlist answer

Answer 1

Answer:

x=2, x=5

Step-by-step explanation:

It’s easier to factor and get the answers:

(-x+5)(x-2)

So x=2, x=5

But if it must be done by quadratic formula:

x=(-7±(√7²-4(-1)(-10))/2(-1)

x=(-7÷√9)/-2

x=(-7±3)/-2

x=4/2, x=10/2

x=2, x=5
