2*2+4x-9=0 4x=9-4 4x=5 x=5/4
2X2 + 3X - 4 = 0the discriminant is,b2 - 4ac32 - 4(2)(- 4)9 + 32 = 4141 > 1this means there are two real roots to this equation
2x2=4
Rearrange: 4x5 + 6x2 + 6x3 + 9 Group: 2x2 (2x3 + 3) + 3 (2x3 + 3) Simplify to get your answer: (2x2 + 3) (2x3 + 3)
The discriminant is 88.
2 x 2 = 4 4 - 9 = -5 -5 + 4 = -1
It is: 3(t+3)
The factorisation is as follows: 2x2 + 7x - 9 = (x - 1)(2x + 9).
2*2+4x-9=0 4x=9-4 4x=5 x=5/4
2x2 + 17x - 9 = 2x2 + 18x - x - 9 = 2x(x + 9) - 1(x + 9) = (2x - 1)(x + 9)
The discriminant is 88.
2X2 + 3X - 4 = 0the discriminant is,b2 - 4ac32 - 4(2)(- 4)9 + 32 = 4141 > 1this means there are two real roots to this equation
