Solve the equation by using the quadratic formula round to the nearest tenth if needed 10x^2-5x-25=0 a) the solutions are about -5.2 and 2.5 b) the solutions are about -1.8 and 2.3 c) the solutions are -2 and 1 d) the solutions are about -1.4 and 1.9 e) the solutions are -5 and 10

D. Use the quadratic formula to get roughly these numbers.

Can u send a screenshot of it? !

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
