4x2 + x2 = 8 + x2

8 (eight)

124 (?) Try to do it on the calculator on your computer * * * * * No, 4x2 + 14x + 12 is factorised, as follows: 4x2 + 14x + 12 = 2(2x2 + 7x + 6) = 2(x + 2)(2x + 3).

7x3 is equal to 21.

Terms like 2x and 4x2 are not like terms. In order for terms to be like terms, they must have the exact same variables with the exact same exponents on them. This means that 5x3 and 7x3 are like terms, but 2x and 4x2 are not. To add or subtract like terms, simply add or subtract the coefficients (the numbers in front) and keep the variable part the same. For example, 5x3 + 7x3 = (5 + 7)x3 = 12x3, and 3x2 + 6x2 = (3 + 6)x2 = 9x2. But, since 2x and 4x2 are not like terms, 2x + 4x2 = 2x + 4x2. It just cannot be simplified any more than that.

The four solution values of x of 3x4 + 7x3 + 4x2 = 0 are: x = -11/3, -1, 0 (repeated) 3x4 + 7x3 + 4x2 = 0 ⇒ x2(3x2 + 7x + 4) = 0 ⇒ x2(3x + 4)(x + 1) = 0 ⇒ x2 = 0 → x = 0 (repeated) or (3x + 4) = 0 → x = -4/3 = -11/3 or (x + 1) = 0 → x = -1

4x2 plus 3=11

y=4x2+3x+8

4x2 + x2 = 8 + x2

4x2+20x+25 (2x+5)^2

4x2 + 12x + 5 = (2x + 1)(2x + 5).

8x3 + 4x2 + 6x + 3 = 4x2(2x + 1) + 3(2x + 1) = (2x + 1)(4x2 + 3)

x3 + 4x2 + x + 4 = (x + 4)(x2 + 1)

x3 + 4x2 + 6x + 24 = (x2 + 6)(x + 4)
