The unmarked angle is equal to b since PQ = RQ and the base angles will be equal
b+140 = 180 since the angles form a straight line
b = 180-140
b = 40
y = (x+5)(x+2)
we are given the following the quadratic function and we are to rewrite it in intercept or factored form:
we can factorize the given quadratic function such that when multiplied, the factors give a product of 10 and when added, they give a result of 7.
therefore, the factored form of the given function is y = (x+5)(x+2).
