Answer:
2x2x2x3x3
Step-by-step explanation:
Quadratic Formula = -b +- √b²- √4ac all over 2a
2w² - 28w = -98
+98 +98
2w² - 28w + 98 = 0
The equation has to be set to ax² + bx + c = 0 in order to use the quadratic formula.
= - (-28) +- √(-28)² - √4(2)(98) ÷ 2(2)
= 28 +- √784 - √784 ÷ 4
= 28 +- 0 ÷ 4
= 28 ÷ 4
= 7
There is only one solution because the discriminant is 0.
