Factor the equation. Remember the value should add to the b value and multiply to the c value.
x^2-x-12= 0
(x-4)(x+3)=0
Use the zero product property to find roots
x-4=0
x=4
x+3=0
x=-3
Final answer: x=-3, x=4
Okay, let's use some math..
So multiply first..
2.99 * 5 = $14.95 that she has spent on gas..
23 / 5 = 4.6 gallons of gas left..
But this question is asking how much she had spent on gas, so your answer will be..
She has spent $14.95 on gas..
You can correct me if I'm wrong..
I hope this helps you!
Factoring the common factor (n-3) from the terms on the left side, that left-side expression becomes
(2n^2-4)(n-3)
We presume your missing factor is
(2n^2-4)
1)
x^2 + (3y/2z) = 7
2x^2z + 3y = 14z
3y = 14z - 2x^2z
3y = 2z(7 - x^2)
y = 2/3(z)(7 - x^2)
2)
(3zx^4) /(5+z) = 2y
3zx^4 = 2y(5+z)
3zx^4 = 10y + 2yz
