Question

Solve 20x2 + 70x + 20 = 0.
Answer

x equals the quantity of 70 plus or minus the square root of 33 all over 4

x equals the quantity of negative 70 plus or minus the square root of 33 all over 4

x equals the quantity of negative 7 plus or minus the square root of 33 all over 4

x equals the quantity of 7 plus or minus the square root of 6 all over 4

Answer 1

20x^2 + 70x + 20 = 0
10(2x^2 + 7x + 2) = 0
\[x = \frac{-b ± \sqrt{b^{2} - 4ac}}{2a}\] where a = 2, b = 7, and c = 2

Answer 2

Okay, then solve?

Answer 3

I'm not so good at that part

Answer 4

Yes. Plug in the values and that should lead you to the answer.

Answer 5

\[x = \frac{-7 ± \sqrt{7^{2} - 4(2)(2)}}{2(2)}\]
Can you simplify and tell me what you get?

Answer 6

Yes, one sec.

Answer 7

\[-7 \pm \sqrt{33} \div 4\]

Answer 8

well over 4
