Question

the product of two consecutive positive integers is 90 form the quadratic equation​

Answer 1

Answer:

Because product is a key word for multiplication, the equation is x(x + 1) = 90. Multiply by using the distributive property on the left side of the equation: x2 + x = 90. Put the equation in standard form and set it equal to zero: x2 + x - 90 = 0
