Question

Find the polynomial =p(x)=x²+7x-30

Answer 1

Answer:

x^2+7x-30

x^2+10x-3x-30

x(x+10)-3(x+10)

(x-3)(x+10)

x-3=0

x=3

OR

x+10=0

x=-10

This method is known as mid-term factorisation

Therefore, values of x are 3,-10

Answer 2

Answer:

answer is here

Step-by-step explanation:

let a = 3

according to the question, x^2 + 7x - 30

=(3)^2 + 7×3 -30 = 9 + 21 - 30 = 30 - 30 = 0

•°• the value of x is 3.

bhai aapka question wrong hai. find the polynomial nahi find the value of x, question hona chahiye
