Question

factorize
$x ^{2} + 7x - 98$
​

Answer 1

Step-by-step explanation:

x²+7x-98

x²+14x-7x-98

x(x+14)-7(x+14)

(X+14)(X-7)

Answer 2

Answer:

-7+√45/2 and -7-√45/2

Step-by-step explanation:

(by using quadratic formula)

a= 1 ( coofecient of x^)

b= 7 ( coofecient of x)

c= 98(constant)

quadratic formula:-

x= -B+/- √D/2A

where D= B^-4A

=(7)^ - 4(1)

= 49 - 4 = 45

putting value of D in quadratic formula

x= -B+/- √D /2A

x= -7+√45/2 and x= -7-√45/2
