I am assuming you made a typing error and are dividing 2x^2+7x-3 by 2x+5. When you do that with long division, 2x goes into 2x^2 x times. x times 2x is 2x^2 and x times 5 is 5x. Subtracting that gives us -2x. Bring down the 3 and divide 2x into -2x to get 1. Multiply 1 times -2x to get -2x and 1 times 5 to get 5. Subtract that and you have a remainder of 2. The quotient is x - 1, with a remainder of 2, or
I don't know how to do the stuff in bold, but he made 28 out of 35 shots
Answer:
x = 6 and -6
Step-by-step explanation:
x²-36 = 0
isolating x
x²-36+36 = 0+36
x²=36
√x² = √36
x = ±6
