2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1

2x2 + 10 - 9x = 0 or 2x2 - 9x + 10 = 0 So (x - 2)*(2x - 5) = 0

If 2x2 + 10 = 100 then: 2x2 = 100 -10 2x2 = 90 x2 = 90/2 x2 = 45 x = 6.708 (to 3 decimal places only)

no

To solve for x: 2x2 + 10 = 58 2x2 = 48 x2 = 24 x = √24 x = √4 × √6 x = 2√6

"Equals" means "the same as." eg 4 = 2x2; four is the same as 2x2. eg "I am your intellectual equal"; our intellects are the same.

Yes, because 2x2 equals 4 and 4/2 equal 2
