-3x2 + 22x = 0 You start by dividing both sides by x: ∴ -3x + 22 = 0 Then rearrange to solve for x: ∴3x = 22 ∴ x = 7 + 1/3
Multiplicand or factor.
x3 - 3x2 + x - 3 = (x - 3)(x2 + 1)
3X2 + 6X + 9 3(X2 + 2 + 3) -----------------------3 is a common factor of all terms
no 3x2=6 then 4x-15= -60 so 6 added with - 60 = -54
-3x2 + 22x = 0 You start by dividing both sides by x: ∴ -3x + 22 = 0 Then rearrange to solve for x: ∴3x = 22 ∴ x = 7 + 1/3
One factor is 3.
3x2 + 27x +60
3x2=6+38=44
-8x + 3x2 - 3
3x2 + 17x + c = 0, rearranging gives c = -3x2 - 17x
3x2 + 48 + 192 = 3x2 + 240 = 3 (x2+ 80)
In general, no.
Multiplicand or factor.
x3+3x2-22x-90 divided by x-5 equals x2+8x+18 For the answer to be correct then the quotient multiplied by the divisor must be equal to the dividend. Hence:- (x-5)*(x2+8x+18) Multiplying out the brackets term by term: x3-5x2+8x2-40x+18x-90 Collecting like terms in descending order: x3+3x2-22x-90 So the answer is correct.
y2=x3+3x2
3x2+13x-10 = (3x-2)(x+5) when factored
