" 5."x^(2)+7x-98

x^(2)-7x-5=0

Add: 5x^(2) - 7x + 3, -8x^(2) + 2x -5 and 7x^(2) - x - 2

Add 7x^(2) -8x + 5, 3x^(2) -8x +5 and -6x^(2) + 15x - 5

From the sum of 6x^(4) - 3x^(3) + 7x^(2) - 5x + 1 and -3x^(4) + 5x^(3) - 9x^(2) + 7x - 2 subtract 2x^(4) - 5x^(3) + 2x^(2) - 6x - 8

The sum of 5x^(2) ,7x^(2) ,8x^(2) ,11x^(2) and 9x^(2) is …………..

Simplify: 5x - 2x ( x- 1) A. 3x - 2 B. 3x + 2 C. 7x + 2x^(2) D. 7x - 2x^(2)

factorize : x^2+7x-98
