2x2-7x+3 = 0 (2x-1)(x-3) = 0 x = 1/2 or x = 3
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
x=6
The Y intercept of y=7x+10 is 10.
7x + y + 3 = y7x + 3 = 07x = -3x = -3/7
x2 + 7x = 2x2 + 6 x2 - 2x2 + 7x = 6 -x2 +7x - 6 = 0 or alternatively x2 - 7x + 6 = 0
2x2 + 7x - 15 = (2x - 3)(x + 5)
2x2-7x+3 = 0 (2x-1)(x-3) = 0 x = 1/2 or x = 3
x2+7x=-2x2+6 3x2+7x-6=0 (3x-2)(x+3)=0 3x-2=0 or x+3=0 x=2/3 or x=-3
(2x + 1)(x + 3) = 0; x = -0.5 or -3
2x2 + 7x = 0 => x(2x+7)=0 so x = 0 or 2x+7 = 0 ie x = 0 or x = -7/2
The answer is x=0
The factorisation is as follows: 2x2 + 7x - 9 = (x - 1)(2x + 9).
It is a linear equation in x. 10x = 7x + 15 3x = 15 x = 5
7x(3x3 - 2x2 + 5x + 1)
2x2 + 7x + 3 = (2x + 1)(x + 3)If 2x2 + 7x + 3 = 0 then:(2x + 1)(x + 3) = 0⇒ (2x + 1) = 0 → x = -1/2or (x + 3) = 0 → x = - 3
It is 2x2 - 7x + 9
